I'll start by saying the issue may be it is far too expensive to enable Tor reporting, due to flooding and other report abuse shenanigans. However, the end result is you are training your users not to care. Vgrep -v works fine for me, know what I mean?

Perhaps what is needed is a slightly more restrictive system for Tor reporting. Maybe a reporting signon for slight accountability? I would not mind mild inconvenience to make a report, but I'm not dropping into the clearnet to do so.
